The Philippine crocodile (Crocodylus mindorensis), also known as the Mindoro crocodile, the Philippine freshwater crocodile or locally, bukarot, is one of two species of crocodiles found in the Philippines; the other is the larger saltwater crocodile (Crocodylus porosus). The Philippine crocodile, the species endemic only to the country, became data deficient to critically endangered in 2008 from exploitation and unsustainable fishing methods, such as dynamite fishing. Conservation methods are being taken by the Dutch/Filipino Mabuwaya foundation, the Crocodile Conservation Society and the Zoological Institute of HerpaWorld in Mindoro island. It is strictly prohibited to kill a crocodile in the country, and it is punishable by law.

Taxonomy and etymologyEdit
The Philippine crocodile is a crocodilian endemic to the Philippines. It is a relatively small, freshwater crocodile. It has a relatively broad snout and thick bony plates on its back (heavy dorsal armor). This is a fairly small species, reaching breeding maturity at 1.5 m (4.9 ft) and 15 kg (33 lb) in both sexes and a maximum size around 3.1 m (10 ft). Females are slightly smaller than males. Philippine crocodiles are golden-brown in color, which darkens as they mature.
Distribution and habitatEdit
The Philippine crocodile has been extirpated in Samar, Jolo, Negros, Masbate, and Busuanga. Populations still survive in the Northern Sierra Madre Natural Park within the Luzon rainforest, San Mariano, Isabela, Dalupiri island in the Babuyan Islands, Abra (province) in Luzon and the Ligawasan Marsh, Lake Sebu in South Cotabato, Pulangi River in Bukidnon, and possibly in the Agusan Marsh Wildlife Sanctuary in Mindanao. It was historically found in parts of Visayas and until the numbers were drastically cut by, mainly, habitat destruction. These Crocodiles eat ailing fish in a significantly higher proportion than healthy fish, thus improving the common health of the fish stock. By preying on the most common fish, they balance the fish population; any species which suddenly becomes dominant is put back in its proper proportion. Crocodile droppings are nutritious for the fish and contain critically important chemicals.
This crocodile is one of the most severely threatened crocodilian species. Roughly 250 are left in the wild as of September 2011 according to an article in National Geographic. Although this species was once found over the whole of the Philippines, it is now critically endangered. In addition, very little is known about the natural history or ecology of the species, or its relationship with Crocodylus porosus, whose range it overlaps. More surveys are required to determine the present range. Initial population reduction was through commercial exploitation, although the current threat is mainly from removal of suitable habitat for agricultural purposes to satisfy a rapidly expanding human population. Governmental support for any conservation measures is limited, and the crocodiles are often killed by the local populace. This situation needs to be changed through awareness programs. Long-term captive breeding and release (through PWRCC, Silliman University, and international breeding centres) is judged to be the best course to take at present, although a management program is imperative for the remainder of the wild population (most of which reside in only one protected area). In 1992, fewer than 1000 animals were estimated to remain in the wild. In 1995, that estimate was revised to be no more than 100 nonhatchlings (hatchlings are rarely counted in surveys because their survival rate is so low). One of the threats to the diminishing population of Philippine crocodile is because it is misunderstood. In mainstream Filipino society, crocodiles are considered dangerous man- eaters and compared to corrupt government officials and law enforcers. They are respected by indigenous community, like a research conducted among permanent residence of Lake Panlabuhan, a tributary of the famous Agusan Marsh, the acceptance of the crocodiles among these residence is very high and theyir risk perception is very low. However, the crocodile have an image problem with outsiders. To many they are viewed as man eaters. In reality, the crocodile is small and will not attack people unless provoked.
In 2007, a specialist group was founded by several people within the Philippines, involved in crocodilian conservation. The Crocodile Conservation Society Philippines and the Zoological Institute of HerpaWorld are working on conservation breeding and release programs. C. mindorensis was considered locally extinct in part of its former range in northern Luzon until a live specimen was caught in San Mariano, Isabela, in 1999. That individual, nicknamed 'Isabela' by its captors, was given to the care of the Crocodile Rehabilitation Observance and Conservation until it was released in August 2007. The specimen was 1.6 m long at the time of its release.
The Philippine crocodile became nationally protected by law in 2001 with the enactment of Republic Act 9147 known as the Wildlife Act. It is punishable to kill a crocodile, with a maximum penalty of ₱100,000 (equivalent to about $2,500). The Philippine Senate introduced resolution no. 790 on May 31, 2012, to further strengthen and augment existing laws for the protection of the Philippine crocodile and the saltwater crocodile.
This crocodile was featured in National Geographic's Dangerous Encounters hosted by crocodile specialist Dr. Brady Barr. In one of the episodes, Barr was seeking to be the first person to see all species of crocodiles in the world. Fortunately, he was able to see a Philippine crocodile only about two weeks old.
The hatching of a Philippine crocodile was recorded in GMA News Born to Be Wild. They recorded that tropical fire ants, an invasive species, eat unhatched endangered bukarot eggs. The media team saved a nest from a fire ant attack. They also recorded adult Philippine crocodiles.
